parsers.c: remove warning: 'size' may be used uninitialized in this function Some compilers / compiler options (such as gcc 4.7) would emit warnings: mercurial/parsers.c: In function 'pack_dirstate': mercurial/parsers.c:306:18: warning: 'size' may be used uninitialized in this function [-Wmaybe-uninitialized] mercurial/parsers.c:306:12: warning: 'mode' may be used uninitialized in this function [-Wmaybe-uninitialized] It is apparently not smart enough to figure out how the 'err' arithmetics makes sure that it can't happen. 'err' is now replaced with simple checks and goto. That might also help the optimizer when it is inlining getintat().

      Corrupt an hg repo with two pulls.

      create one repo with a long history

        $ hg init source1

        $ cd source1

        $ touch foo

        $ hg add foo

        $ for i in 1 2 3 4 5 6 7 8 9 10; do

        >     echo $i >> foo

        >     hg ci -m $i

        > done

        $ cd ..

      create one repo with a shorter history

        $ hg clone -r 0 source1 source2

        $ cd source2

        $ echo a >> foo

        $ hg ci -m a

        $ cd ..

      create a third repo to pull both other repos into it

        $ hg init corrupted

        $ cd corrupted

      use a hook to make the second pull start while the first one is still running

        $ echo '[hooks]' >> .hg/hgrc

        $ echo 'prechangegroup = sleep 5' >> .hg/hgrc

      start a pull...
